摘　　要：文章利用改进了油滴的碰撞子模型KIVA-3V程序对16V240ZJB型柴油机在标定工况下的压缩和燃烧过程进行了模拟。研究分析了涡流比和和缸内湍能分数对燃烧和排放的影响。结果表明涡流比是影响燃烧和排放的关键。The 3D simulation of working process with KIVA-3V modified was achieved on standardization work condition of the 16V240ZJB engine. The paper analyzes the effect of swirl and turbulence kinetic energy on exhaust emission and combustion of diesel engine. The result shows that the swirl has effect on combustion of diesel engine.
